We are going to continue our systematic solution to diagnosing a pool heater by hunting at how to proceed calibrated temperature probe when the light while in the handle pad within the top of your Sta-Rite pool and spa heater that's labeled “service heater” is lit. (We are going to move forward with all the assumption you know almost everything from section a single.) This time you will need to get rid of the perimeters from the heater in advance of disconnecting power towards the heater to be able to browse the codes within the board connected for the topside. Soon after eradicating the perimeters, you will note the massive topside that may be nevertheless connected to the heater. Down below the topside is usually a metallic panel that keeps the topside in position. Beneath this panel there are two locking pins (cotter pins). Cautiously take out the two pins and retail outlet them someplace harmless till reassembly. Gently take away the top and turn it upside down. You will notice a lightweight lit over the board you happen to be on the lookout at when you switch the topside above. The light will be beside a code which is published on the board.

The first code that you will see on the still left side with the board will probably be PS. This is the code with the strain swap. We protected the force change in section a person. If this light-weight is lit return to section just one and review that section. If necessary stick to the guidance to exchange the force switch.

Another code you'll see on the board is HLS. For those who have a controller to the process you must bypass it presently. You must carefully disconnect the facility within the heater. After you are guaranteed the ability is disconnected, you will have to locate and open the high-voltage cabinet. This cabinet is really a metal box in the course of the heater. If you are looking within the cupboard, there is certainly normally a screw to the top rated ideal side. Loosen the screw and also the doorway will swing down toward you. You require to get exceptionally very careful when doing work in this box and only do so if you are absolutely sure which the electric power for the heater is OFF.

You need to bypass the firewall basic safety interface. To accomplish this you may have to have a shorter wire with stab-tab connectors. Should you have got a controller and it was thoroughly mounted the wire can have been remaining inside the box from the tech who installed the controller. If not you must make this jumper wire. At this stage look in your owner's manual to locate the 2 appropriate pins to connect to. In case you possess a controller or are using a fireman's change this is where your manage should be connected. When you have a controller and it really is not related here, it could be the resource of your issues and possibly use a certified tech suitable the problem or accurate it yourself.

You have to be mindful not to place the jumper wire within the electrical power terminals otherwise you will demolish your heater by burning up the electronic technique. Use your manual to identify the place the fireman's change is meant being hooked up and thoroughly attach your jumper involving these terminals. Should you now activate the ability as well as the heater is effective with none problems, your problem lies inside the controller or the wiring going to the controller. You need to hassle shoot this system.

Should you nonetheless hold the exact difficulty along with your heater. (“service heater” gentle arrives on), depart the jumper set up and confirm that the pump is on which you've got superior drinking water movement. Ensure once again along with your meter which the stress swap isn't cycling. It must read through being a dead quick. (See phase one particular) With superior water movement verified and also the “service heater” light-weight on, your issue may very well be one of the thermo-regulators in the safety program.
